I have version 1.2.9 lite version on my device. I purchased mobile security 2.5 and when I attempt to enter the activation key, it's rejected, saying there is a problem with activation key. I've typed it manually and cut and paste. I would appreciate any help anyone could give me. I called Support and they tell me "There is no support for Iphone 5" I don't understand Symantec selling a product without any support. Help!
